Vector Control and Dynamics of AC Drives VSD for Extrusion Machines

Extrusion machines are used to create product by forcing raw material, such as plastic, through a die. Extruders are used to create a wide range of products such as tubing, sheet goods, and insulation. Food processing is a popular application for extruders. Extruders employ a main drive motor to supply power to a screw, which provides the force necessary to push the raw material through the die.

Application Challenges

· Replace hydraulically operated or DC powered drives

· Precise speed control while material is being extruded

· Develop high torque at very low speeds

Features of V5 series matching lift control application



Excellent Control Performance under Speed Sensorless Vector Control Mode

  • Realizing AC motor decoupling, enabling the DC motorization of operation control.
  • Fig. 1 indicates the four-quadrant operation of the motor under speed sensorless vector control. The torque, current, speed and DC bus voltage have quick response, and the motor has stable operation.
  • Realizing 0.1s acceleration/deceleration with rated motor load.
  • Upon the zero-crossing switching of the motor (forward/reverse switching), the current has no phase mutation or oscillation, and the rotating speed has no pulsation.

The bus voltage is under stable control. Quick and reliable braking can be realized when decelerating under the condition of braking without power consumption.

Realizing Real Tripless Operation

  • With excellent current and voltage control technology, 0.1s repetitive and alternate acceleration and deceleration is performed, and the inverter realizes stable and tripless operation.
  • With extremely powerful loading capacity, the inverter can realize stable tripless operation in any acceleration/deceleration time and under any impact load condition.
  • With strong short-time overload capacity, the inverter can operate continuously for 0.5s under 200% rated load, and 1 minute under 150% rated load.
  • The intelligent module temperature control maximizes the loading capacity of the inverter.

Unique Instantaneous Mains Failure Reaction

  • Upon the instantaneous mains failure, the energy of the motor feedback bus will keep the inverter running till the mains resumes normal.
  • When shutdown is caused by long-term power-failure during the operation of the inverter, the inverter will provide alarm message after power resumes normal.
  • It supports the automatic operation after power-up.
  • The deceleration time during the power failure and the acceleration time after the power recovery can be set independently.

Unique Speed Tracing Function

  • It doesn’t need special hardware detection circuit and no special function code to be set. Within the range of 0 to 60Hz, the inverter can complete identification the motor rotating speed, rotating direction and phase angle within 0.2s, and start smooth tracing on the freely rotating motor.
  • Tracing mode 1: Quick and smooth tracing on the free speed motor without any impact.
  • Tracing mode 2: Impactlessly pull down the motor from high-speed to low speed and then accelerate to normal speed.

Unique Quick DC Braking

  • Within the range of 0 to 300Hz, the inverter can realize back electromotive force elimination and quick DC braking within 0.3s.
  • DC current input in the most efficient way to improve the braking capacity.
  • There is no initial waiting time for the DC braking.
  • Special function code of the initial waiting time for DC braking setting is cancelled.

A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
